S3:在氮气保护下,向反应容器中加入1,4-二恶烷(141.4 L)、钯催化剂Pd(PPh3)4(3.9 kg)和水(70.68 L),随后加入N-(6-(4,4,5,5-四甲基-1,3,2-二氧杂硼杂环戊烷-2-基)萘-2-基)甲磺酰胺(23.56 kg)和1-(3-(叔丁基)-5-碘-4-甲氧基苯基)嘧啶-2,4(1H,3H)-二酮(27.13 kg),搅拌混合。接着加入碳酸钠(8.63 kg),将反应溶液保持4-6小时,期间通过TLC监测反应进度直至反应完成。反应完成后,将反应溶液冷却至40℃,然后用乙酸乙酯(235.6 L)稀释。合并的有机相用水(47.12 L)洗涤,随后在50℃下减压蒸馏浓缩有机相。粗产物中加入乙酸乙酯(94.24 L),在50-60℃下搅拌30分钟,最终得到粗产物(29.45 kg)。粗产物经过抽滤后,通过硅胶柱色谱法进行纯化。该取代反应为单一步骤,产率为76.5%。
